This is the first time to answer a question that Baidu knows about. The registration of trademarks is usually done by agencies. It is very important to query the agencies. If you are not sure about their query results, it is best to search on Baidu. "Bozheng Trademark Platform" has a relatively powerful online query function. If you submit a query online, a query report will usually be available in about 10 minutes. They also provide services for submitting trademark registration applications online. You can consult the platform staff. I hope my answer helps you
